This video shows you how to build your own external portable battery pack for smartphones and tablets.
And do it cheaply.

Someone complained that since usb voltage is 5 volts, 4 x 1.5v AA batteries would be 6 volts.
The design did not include a way to reduce that voltage to 5 volts.
Note that four NiCad or NiMH AA batteries would yield the correct voltage.
But the video has been pulled.
